HARRY M. ACLY, OF PITTSFIELD, MASSACHUSETTS, ASSIGNOR TO STANLEY ELECTRIC MANUFACTURING COMPANY, OF PITTSFIELD, MASSACHU- SETTS, A CORPORATION -OF NEW JERSEY.

DYNAMO-ELECTRIC MACHINE.

SPECIFICATION forming part of Letters Patent No. 737,192,`dated August 25, 19 03. Application filed January 3l, 1903. Serial No. 141,354. (No model.)

To l/ZZ whom it may concern:

Be it known that I, HARRY M. ACLY, a citizen of the United States,residing in Pittsiield, in the State of Massachusetts, have invented 5 certain new and useful Improvements in the Construction of Dynamo-Electric Machines, of which'the following is a specification.

My invention relates to the construction of dynamo-electric machines. -Itsobject is to 1o provide a simple means for efficiently retaining the coils in the machine and yet allowing the quick and easy removal of defective coils and the substitution of new ones.

Referring to the drawings, Figure l is a development in plan view of a machine embodying my invention, and Fig. 2 isa development in elevation of the same.

A represents the frame on which the coils B B B are mounted. The frame is built up zo of laminations, and the coils are embedded in slots therein. C is a cast iron or steel ring pressed against the laminations and'holding them compressed in place. D D D are lugs cast on ring C. These lugs are drilled to re- 2 5 ceive the screws E E E. F F F are clamps of non-magnetic metal held at their center to lugs D D D by means of screws E E E and at their ends bearing down upon and retaining in place the coils B B B. Between the 3o clamps F F F and the coils are inserted thin blocks H H H of insulating material, such as micanite, paper fiber, &c.

The construction as set forth in the drawings is simple, is efficient for firmly retaining` the coils, is well adapted for permittingr their quick removal, and does not interfere with the most efficient design and operation of the machine.

My invention is capable of various modifications which will occur to those skilled in 4o the art to which it pertains without departing from the essential features thereof. Therefore I do not limit myself to the particular construction or arrangement of parts shown and described. 45

Having thus fully described my invention, what I claim, and desire to protect by Letters Patent, is-'-4 l. In a dynamo-electric machine, a frame built of iron laminations, coils located in slots 5o therein, "end plates for retaining the laminations, lugs on the end plates, and non-magnetic clamps secured to said lugs and retaining the Vcoils in position.

2. In a dynamo-electric machine, a frame built of iron laminations, coils located in recesses therein, end plates for retaining the laminations, lugs on said end plates, and nonmagnetic clamps secured at their center to said lugs and at their ends bearing on and re- 6o taining the coils in position".

3. In a dynamo-electric machine, a frame built of iron laminations, coils located in recesses therein, end plates for retaining the laminations, lugs on said end plates between the coils, and non-magnetic clamps secured to said lugs and retaining the coils in position.

In testimony whereof I Ahave signed my name to this specification in the presence of two subscribing witnesses.

HARRY H. ACLY.
